ASSIGNOR TO AMERICAN A VOLUNTARY ASSOCIA- OPHTHALMIC MOUNTING.

To all whom it may concern:

Be it known that I, ELMER L. SCHU- MACIIER, a citizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improve ments in Ophthalmic Mountings, of which the following is a specification.

This invention relates to improvements in ophthalmic mountings and has particular reference to an im roved construction of What is commonly own as the Windsor type, that is to say a mounting having an inner metallic rim and an outer ornamental, preferably non-metallic ortion.

One of the leading. 0b]6CtS of the present invention is the provision of a novel and improved construction whereby a non-metallic ornamental frame member may be readily applied to ordinary constructions of metallic frames without the necessity of changes in the original construction of the frame and witlliput adding additional parts to the frame itse A further object of the resent invention is the rovision of nove and improvled means or firmly and securely retaining a supplemental frame member in position with respect to the main frame without direct attachment or connection of the supplemental frame to the main frame.

A further object of the present invention is the provision of a novel and improved form of frame in which the su plemental portion may be readily removed from the main portion when desired, or in which the supplemental portion will remain in close en agement with the main frame portion [1051 when in use and when the main frame is opened for the insertion or removal of'a lens.

Other objects and advantages of my improved construction should be readily apparent by reference to the following specification taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of my invention.

Fig. II represents a fragmentary enlarged perspective view of the rear face thereof.

Fig. III represents a fragmentar vertical sectional view of the construction i .lustrated in Fig. II.

Fig. IV represents a view similar to Fig. III of a spring type of construction.

Fi V represents a pers ective view of the (fevice shown in Fig. I as applied to the frame.

Fig. VI represents a sectional view of another modified form of my invention.

Fig. VII represents a view in elevation thereof.

In the drawings, in which similar characters of reference are employed to denote corresponding parts throughout the several views, the numeral 1 designates the bridge of one of my improved mountings, which bears at each end the metallic lens frame 2, adapted to receive the lens 3, and provided with the end piece members 4, connected as by the screw 5 which serves to hold the end pieces together and thus retain the lens within the frame 2 and at the same time the screw 5 may afford a pivot for the temple member 6.

Surrounding each of the metallic frame members 2 is a supplemental ornamental preferably non-metallic frame portion 7 having a central groove as at 8 into which fits the member 2. p In the form of my invention illustrated in Figs; II and III for example, I have shown each end of the frame 7 as provided with the pair of connecting plates or wires 9 having their ends embedded as at 10in the material of the frames, and having th ir adjacent ends formed with alined apertures adapted to receive the securing screw 11.

In the use of this form of my invention the supplemental frame 7 is fitted around the main frame 2 and its ends brought into close engagement with the end pieces 4 when the apertures of the connecting memhere at each side will register and may have passed therethrough the fastenin screws 11, which secure the plates toget er and thus firmly hold the supplemental frame in place around the main frame, althou h there is no direct connection between t e main and supplemental frames. It is to be noted, however, that in the form of the invention illustrated in Figs. II and III, I have shown the end piece members recessed as at 12 to receive the connections 9,'but it will be understopd that this form ofconstruction is par icularly adaptable for use when frames are being put out new as an entirety, and that by slig tly different bending of the members 9 they may substant1ally fit around the ordinary end ieces now on the market and thus allow my improved supplemental frames to be fitted onto present day commercial spectacles or eyeglasses without alteration or modification thereof.

In Figs. IV and V, I have shown a further form of my invention for accomplishing the same result. In this form I have shown the U-shaped clips 13 centrally embedded in and passing through the non-metallic frame 7 near each end and terminating in eyes 14, the eyes of the clips being connected at each side as by the springs 15, which may either fit around the end pieces or into the recess 12 therein, these springs in either instance holding the frames 7 around the metallic frames 2 under tension so that the will at all times be properly retained in p ace. On the other hand when it is desired to remove the frames 7 from the frames 2 it is merely necessary to stretch open the joint, which on accou t of the 5 rings will have sufiicient expansion to a 0w the supplemental frame to be snapped off the main frame, and when it is desired to insert a lens it is only necessary to loosen the screw 5 and separate the end pieces and the stretch of the spring will allow sufficient separation for changin the lens without necessity of removal of t e supplemental frame.

In Figs. VI an VII, 1 have illustrated an extremely novel frame adapted to be constructed de no vo for my improved mounting, s in this event there is embedded in each end of the frame 7 the head 16 of the split screw member 17, the two half screw members overlapping each other through the end iece sections 4, and being drawn into over apped relation throu h rotation of the nut 18. It is to be noted t at the members 17 are further provided with the shoulders 19 adapted in connection with the ends of the frame 7 to bear against the outer face of the end pieces so that as the screw sections are drawn into overlapped relation by rotation of the nut they will draw together the end pieces and tighten the main and supplemental frames around the lens to seciire the several parts together. At the same time if desired the temple 6 may be pivoted on the half screw sections and in this form but a single fastening device at each end of the frames 7 serves to provide a pivot for the temple, a fastening means for the non-metallic frame and a fastening means for the metallic frame, although in this, as in all other forms of my invention the connection is between the two ends of the non-metallic frame and there is no direct securin of the ends of the non-metallic to the meta lic frame or to the end pieces, though the proper connection of the two ends of the frames7 will absolutely prevent disenagement of the frames 7 from the metallic rame 2 without severe distortion of the metallic frame.

It will, of course, be understood that not only is the form of my invention shown in Fig. VI ada ted to lock the end piece membars 4 to er, even though the screw 5 be remove ,but similarly in all other forms illustrated if the tension of the springs be sufiicient they will hold the parts together without connection of the en pieces.

In connection with the form illustrated in Fig. 11 it is not necessary in an ordinary frame that the connections be placed on both sides of the joints of the ends of the frame member 7, but if desired the front cross member or connection may be dispensed with and the rear one only used, thus making a more sightly mounting when same is viewed from the front.

I claim:

1. An attachment for an ophthalmic mounting comprising a split non-metallic rim member having an interior groove to receive the mounting and means connectin the ends of the attachment independent 0 the mounting.

2. The combination with a spectacle mounting having endpieee members projecting outwardly therefrom, of an attachment for the mountin in the form of a split rim having its en spaced to receive t e endpiece therebetween, and means independent of the endpiece for connecting the ends of the attachment to each other.

3. An attachment for an ophthalmic mounting comprising a relatively non-resilient split supp emental frame member and resilient means connecting the ends of the frame member.

4. An attachment for ophthahnic mountings comprising a supplemental composition rim member interiorly grooved to fit the mounting and split at one side, and a resilient or spring connecting device drawing the ends of the attachment toward each (if er to retain the device in position'on a ame.
